ABSTRACT

The invention relates to novel phenyl-substituted cyclic ketoenols of the formula (I)in whichA, B, G, X, Y, Z and W are each as defined in the description,to processes and intermediates for their preparation and to their use as pesticides and herbicides.

This application is a divisional application of U.S. patent application Ser. No. 09/530,883 filed May 8, 2000, now U.S. Pat. No. 6,608,211 Issue Fee paid Mar. 28, 2003, which in turn was the national stage of PCT/EP98/06866 filed Oct. 29, 1998.

The invention relates to novel phenyl-substituted cyclic ketoenols, to a plurality of processes and intermediates for their preparation and to their use as pesticides and herbicides.

It is already known that certain phenyl-substituted cyclic ketoenols are active as insecticides, acaricides and/or herbicides.

1H-Arylpyrrolidine-dione derivatives (EP-A-456 063, EP-A-521 334, EP-A-596 298, EP-A-613 884, EP-A-613 885, DE-44 40 594, DE-196 49 665, WO 94/01 997, WO 95/01 358, WO 95/20 572, EP-A-668 267, WO 95/26 954, WO 96/25395, WO 96/35 664, WO 97/01 535 and WO 97/02 243) and their use as pesticides and, of some of them, as herbicides, are known.

However, the herbicidal, acaricidal and insecticidal activity and/or spectrum of activity and/or plant safety of these compounds, in particular with respect to crop plants, is not always satisfactory.

The dosages of the active compounds according to the invention necessary for controlling weeds are between 0.001 and 10 kg/ha, preferably between 0.005 and 5 kg/ha.

The active compounds according to the invention can be used, for example, in connection with the following plants:

Dicotyledonous weeds of the genera: Sinapis, Lepidium, Galium, Stellaria, Matricaria, Anthemis, Galinsoga, Chenopodium, Urtica, Senecio, Amaranthus. Portulaca, Xanthium, Convolvulus, Ipomoea, Polygonum, Sesbania, Ambrosia, Cirsium, Carduus, Sonchus, Solanum, Rorippa, Rotola, Lindernia, Lamium, Veronica, Abutilon, Emiex, Datura, Viola, Galeopsis, Papaver, Centaurea, Trifolium, Ranunculus and Taraxacum.

Dicotyledonous crops of the genera: Gossypium, Glycine, Beta, Daucus, Phaseolus, Pisum, Solanum, Linum, Ipomoea, Vicia, Nicotiana, Lycopersicon, Arachis, Brassica, Lactuca, Cucumis and Cucurbita.

Monocotyledonous weeds of the genera: Echinochloa, Setaria, Panicum, Digitaria, Phleum, Poa, Festuca, Eleusine, Brachiaria, Lolium, Bromus, Avena, Cyperus, Sorghum, Agropyron, Cycnodon, Monochoria, Fimbristylis, Sagittaria, Eleocharis, Scirpus, Paspalum, Ischaemum, Sphenoclea, Dactyloctenium, Agrostis, Alopecurus and Apera.

Monocotyledonous crops of the genera: Oryza, Zea, Triticum, liordeum, Avena, Secale, Sorghum, Panicum, Saccharum, Ananas, Asparagus and Allium.

However, the use of the active compounds according to the invention is in no way restricted to these genera, but also extends in the same manner to other plants.

The compounds are suitable, depending on the concentration, for the total controlling of weeds, for example on industrial terrain and rail tracks, and on paths and squares with or without tree plantings. Equally, the compounds can be employed for controlling weeds in perennial cultures, for example afforestations, decorative tree plantings, orchards, vineyards, citrus groves, nut orchards, banana plantations, coffee plantations, tea plantations, rubber plantations, oil palm plantations, cocoa plantations, soft fruit plantings and hop fields, on ornamental and sports lawns and meadow areas and for the selective controlling of weeds in annual cultures.

The active compounds according to the invention are particularly suitable for selectively controlling monocotyledonous weeds in dicotyledonous crops by the pre- and post-emergence method. For example, they can be employed very successfully for controlling harmful grasses in cotton or sugar beet.

The active compounds can be converted into the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, dusting agents, pastes, soluble powders, granules, suspension-emulsion concentrates, natural and synthetic materials impregnated with active compound, and very fine capsules in polymeric substances.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents and/or solid carriers, optionally with the use of surface-active agents, that is emulsifying agents and/or dispersing agents and/or foam-forming agents.

If the extender used is water, it is also possible to employ, for example, organic solvents as auxiliary solvents. Suitable liquid solvents are essentially: aromatics, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulphoxide, and also water.

As solid carriers there are suitable:

for example, ammonium salts and ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly disperse silica, alumina and silicates; as solid carriers for granules there are suitable: for example, crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, and also synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust coconut shells maize cobs and tobacco stalks; as emulsifying and/or foam-forming agents there are suitable: for example, non-ionic and anionic emulsifiers, such as polyoxyetlhylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkyl sulphonates, alkyl sulphates, aryl sulphonates and also protein hydrolysates; as dispersing agents there are suitable: for example, lignin-sulphite waste liquors and methylcellulose.

Tackifiers such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latexes, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, and also natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations. Other possible additives are mineral and vegetable oils.

It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations in general contain between 0.1 and 95% by weight of active compound, preferably between 0.5 and 90%, and additionally preferably extenders and/or surfactants.

The active compound according to the invention can be present in its commercially available formulations and in the use forms prepared from these formulations as a mixture with other active compounds, such as insecticides, baits, sterilizing agents, acaricides, nematicides, fungicides, growth-regulating substances or herbicides. The insecticides include, for example, phosphoric acid esters, carbamates, carboxylic acid esters, chlorinated hydrocarbons, phenylureas, substances produced by microorganisms, and the like.

The active compounds can be used as such or in the form of concentrates or generally customary formulations, such as powders, granules, solutions, suspensions, emulsions or pastes.

The formulations mentioned can be prepared in a manner known per se, for example by mixing the active compounds with at least one solvent or diluent, emulsifier, dispersing agent and/or binder or fixing agent, water repellant, optionally siccatives and UV stabilizers, and if appropriate dyestuffs and pigments, and also other processing auxiliaries.

The insecticidal compositions or concentrates used for preservation of wood and derived timber products comprise the active compound according to the invention in a concentration of 0.0001 to 95% by weight, in particular 0.001 to 60% by weight.

The amount of composition or concentrate employed depends on the nature and the occurrence of the insects and on the medium. The optimum amount employed for the use can in each case be determined by a series of tests. In general, however, it is sufficient to employ 0.0001 to 20% by weight, preferably 0.001 to 10% by weight, of the active compound based on the material to be preserved.

The solvent and/or diluent used is an organochemical solvent or solvent mixture and/or an oily or oil-like organochemical solvent or solvent mixture of low volatility and/or a polar organochemical solvent or solvent mixture and/or water and, if appropriate, an emulsifier and/or wetting agent.

The organochemical solvents employed arc preferably oily or oil-like solvents having an evaporation number above 35 and a flash point above 30° C., preferably above 45° C. Corresponding mineral oils or aromatic, fractions thereof or solvent mixtures containing mineral oil, preferably white spirit, petroleum and/or alkylbenzene are used as such water-insoluble, oily and oil-like solvents of low volatility.

Mineral oils having a boiling range from 170 to 220° C., white spirit having a boiling range from 170 to 220° C., spindle oil having a boiling range from 250 to 350° C., petroleum or aromatics having a boiling range from 160 to 280° C., terpentine oil and the like are advantageously employed.

In a preferred embodiment, liquid aliphatic hydrocarbons having a boiling range from 180 to 210° C. or high-boiling mixtures of aromatic and aliphatic hydrocarbons having a boiling range from 180 to 220° C. and/or spindle oil and/or monochloronaphthalene, preferably monochloronaphthalene, are employed.

The organic oily or oil-like solvents of low volatility having an evaporation number above 35 and a flash point above 30° C., preferably above 45° C., can be replaced in part by organochemical solvents of high or medium volatility, provided that the solvent mixture likewise has an evaporation number above 35 and a flash point above 30° C., preferably above 45° C., and that the insecticide/fungicide mixture is soluble or can be emulsified in this solvent mixture.

According to a preferred embodiment, some of the organochemical solvent or solvent mixture is replaced by an aliphatic polar organochemical solvent or solvent mixture. Aliphatic organochemical solvents containing hydroxyl and/or ester and/or ether groups, such as, for example, glycol ethers, esters or the like, are preferably used.

Organochemical binders which are used within the context of the present invention are the synthetic resins and/or binding drying oils which are water-dilutable and/or soluble or dispersible or emulsifiable in the organochemical solvents employed and are known per se, in particular binders consisting of or comprising an acrylate resin, a vinyl resin, for example polyvinyl acetate, polyester resin, polycondensation or polyaddition resin, polyurethane resin, alkyd resin or modified alkyd resin, phenolic resin, hydrocarbon resin, such as indene-coumarone resin or silicone resin, drying plant and/or drying oils and/or binders which dry by physical means and are based on a naturally occurring and/or synthetic resin.

The synthetic resin used as the binder can be employed in the form of an emulsion, dispersion or solution. Bitumen or bituminous substances can also be used as binders in an amount of up to 10% by weight. In addition, dyestuffs, pigments, water-repellant agents, odour correctants and inhibitors or corrosion prevention agents and the like which are known per se can be employed.

Preferably, according to the invention, the composition or concentrate comprises at least one alkyd resin or modified alkyd resin and/or one drying plant oil as an organochemical binder. Alkyd resins having an oil content of more than 45% by weight, preferably 50 to 68% by weight, are preferably used according to the invention.

All or some of the binder mentioned can be replaced by a fixing agent (mixture) or a plasticizer (mixture). These additives are intended to prevent evaporation of the active compounds and crystallization or precipitation They preferably replace 0.01 to 30% of the binder (based on 100% of the binder employed).

The plasticizers originate from the chemical classes of phthalic acid esters, such as dibutyl, dioctyl or benzyl butyl phthalate, phosphoric acid esters, such as tributyl phosphate, adipic acid esters, such as di-(2-ethylhexyl) adipate, stearates, such as butyl stearate or amyl stearate, oleates, such as butyl oleate, glycerol ethers or higher molecular weight glycol ethers, glycerol esters and p-toluenesulphonic acid esters.

Fixing agents are based chemically on polyvinyl alkyl ethers, such as, for example, polyvinyl methyl ether, or ketones, such as benzophenone or ethylenebenzophenone.

Water in particular is also a possible solvent or diluent, if appropriate mixed with one or more of the abovementioned brganochemical solvents or diluents, emulsifiers and dispersing agents.

Particularly effective wood preservation is achieved by impregnation processes oln a large industrial scale, for example vacuum, double vacuum or pressure processes.

After the desired period of time, the kill in % is determined. 100% means that all caterpillars have been killed; 0% means that none of the caterpillars have been killed.

In this test, at an exemplary active compound concentration of 0.1%, for example the compounds of Examples I-c-3, I-a-14, I-c-15, I-a-20, I-c-13 and I-b-24 effected a kill of in each case 100% after 7 days.

EXAMPLE E

Tetranychus Test (OP-Resistant/Dip Treatment)

Solvent: 3 parts by weight of dimethylformamide

Emulsifier: 1 part by weight of alkylaryl polyglycol ether

To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent and the stated amount of emulsifier, and the concentrate is diluted with water to the desired concentration.

Bean plants (Phaseolus vulgaris) which are heavily infested by all stages of the greenhouse red spider mite Tetranychus urticae are dipped into a preparation of active compound of the desired concentration.

After the desired period of time, the kill in % is determined. 100% means that all spider mites have been killed; 0% means that none of the spider mites have been killed.

In this test, at an exemplary active compound concentration of 0.1%, for example the compounds of Examples I-b-2, I-b-3, I-b-4, I-c-3, I-a-4, I-c-1, I-b-7, I-c-4, I-a-7, I-9 and 1-b-8 had an effect of in each case 100% after 14 days, and the compounds of Examples I-b-15, I-b-16, I-b-17, I-b-22 and I-c-13 had this effect at an exemplary active compound concentration of 0.02%.

EXAMPLE F

Critical Concentration Test/Root-systemic Action

Test insect: Aphis fabae

Solvent: 4 parts by weight of acetone

Emulsifier: 1 part by weight of alkylaryl polyglycol ether

To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent and the stated amount of emulsifier, and the concentrate is diluted with water to the desired concentration.

The preparation of active compound is intimately mixed with soil. The concentration of the active compound in the preparation is of practically no importance here, only the amount by weight of active compound per unit volume of soil, which is given in ppm (=mg/l), being decisive. The treated soil is transferred into pots and these are planted with pregerminated broad beans. The active compound can in this way be taken up from the soil by the roots of the plants and be transported into the leaves.

To demonstrate the root-systemic effect, the leaves are populated with the above-mentioned test animals after 7 days. After a further 6 days, evaluation is carried out by counting or estimating the dead animals. The root-systemic action of the active compound is deduced from the mortality figures. It is 100% if all the test animals have been killed and 0% if just as many test insects are still alive as in the case of the untreated control.

In this test, at an exemplary active compound concentration of 20 ppm, for example the compounds of Examples I-a-1, I-b-4, I-a-4, I-b-5, I-a-16, I-b-1, I-b-3, I-c-1, I-c-2, I-b-17, I-b-10, I-a-16 and I-b-25 had an effect of in each case 100%.

EXAMPLE G

Critical Concentration Test/Root-systemic Action

Test insect: Myzus persicae

Solvent: 4 parts by weight of acetone

Emulsifier: 1 part by weight of alkylaryl polyglycol ether

To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent and the stated amount of emulsifier, and the concentrate is diluted with water to the desired concentration.

The preparation of active compound is intimately mixed with soil. The concentration of the active compound in the preparation is of practically no importance here, only the amount by weight of active compound per unit volume of soil, which is given in ppm (=mg/l), being decisive. The treated soil is transferred into pots and these are planted with peppers at the cotyledon stage. The active compound can in this way be taken up from the soil by the roots of the plants and be transported into the leaves.

To demonstrate the root-systemic effect, the leaves are populated with the above-mentioned test animals after 7 days. After a further 6 days, evaluation is carried out by counting or estimating the dead animals. The root-systemic action of the active compound is deduced from the mortality figures. It is 100% if all the test animals have been killed and 0% if just as many test insects are still alive as in the case of the untreated control.

In this test, at an exemplary active compound concentration of 20 ppm, for example the compounds of Examples I-b-10, I-a-16 and I-b-25 had an effect of in each case 100%.
